Harry Potter discussion

Sometimes when I'm reading HP and the GOF I usually daydream but to be honest, I don't know if I'm a daydreamer as I thought I would be due to the fact that I've been garaduated in languagues I end up developing a analytical look on almost everything I read. I guess only people who already have devote their lives to the studies of fregin languages or taken the same course as mine will be albe to get the massage through what I'm trying to say.

For this reason icould realize the defference in the part where Dumblemdore was making his welcome speech to the delegations of Durmstrang and Beauxbatons until he start to explain the rules of the Triwizard Tournement.
Honestly guys, the way the J.K manupulates the language, I mean, the way that she writes gives the clear impression that there's a Headmaster saying wolcome to me is something that makes me feel gobmacked.

What's your opinion let me know!
